sure to pink, and finally to brown. It has a persis- 

 tent, alliaceous odor, and bitter, alliaceous, acrid

Physiological Action. — Asafcetida is a power- 

 ful antispasmodic, a carminative, a stimulating expec- 

 torant, a nerve and cerebral stimulant. It is also 

 mildly tonic, laxative, diuretic, diaphoretic, emmena- 

 gogue, aphrodisiac, and anthelmintic. It raises ar- 

 terial tension, stimulates the circulation, secretions, 

 and excretions, the general nervous system, the men- 

 strual flow, and sexual appetite. Its continued use at 

 times causes impaired digestion, flatulency, difficult 

 urination, diarrhcea, , tenesmus, and phenomena of 

 general nervousness. It is rapidly absorbed and elim- 

 inated by the respiratory mucous membrane, the 

 kidneys, and the skin, gently stimulating their secre- 

 tions. 



Therapeutics. — It has long been successfully giv- 

 en in flatulent colic of the lower animals; in con- 

 stipation — with aloes and nux vomica; in chronic 

 bronchial affections, chronic catarrh — combined with 

 ammonia muriate. Also as a vermifuge, but for this 

 purpose its action is somewhat uncertain.
